Title: Reduction of organic cpds with sodiumboroh- - ydride
IPC: C07C29/143
Filed: 1970-02-27
Abstract: Redn. is effected at low temps. in the presence of a transition metal salts.

Title: Injector/mixing appts with diaphragm pump - for wines and cider in storage tanks
IPC: B01F33/40
Filed: 1972-07-18
Abstract: Appts. is intended for mixing several prods. and then injecting the mixt. into the tanks contg. the materials to be treated, while, at the same time, mixing these materials in a perfect manner. The appts. comprises a cylindrical container with a large autoclave-type opening, a compressor gp. mounted on a tubular chassis with carries an air reservoir; and a magnetic valve, with a wide orifice, which is controlled by a manometric contator.

Title: Rolling mill using rotating ring frames - to give rigid structure and reduce radial stress on bearings
IPC: B21B13/04
Filed: 1974-01-14
Abstract: A mill consists of >=two work-rolls mounted inside two ring frames located coaxially on a base-plate. During operation, the rings rotate together with the work-rolls thus reducing the radial stresses on the bearings. Intermediate, back-up rolls are pref. mounted inside the ring-frames with an adjusting device to control the gap between the work-rolls. High rigidity is obtd. with this design so that rolled prods. can be produced to close tolerances and less complex- and thus cheaper- bearings can be used in the mfr. of the mill.

Title: Card game based on program flow chart - with players picking cards from face down pack
IPC: A63F1/00
Filed: 1974-12-04
Abstract: The card game is based on the principle of a computer program flow chart, the highest accumulation of points by an individual player being the winning objective. Cards are used which have single operations similar to computer instructions, i.e. add 2, add 4, times 2, times 4 or divide 2 etc. Further cards may be introduced at the players' discretion to enable alternative calculation routes to be taken ie. loops etc. The game starts with each of four players having 8 of 9 cards with the rest stacked face down, a player having a debut card making a start and assuming a datum value of 8 points, laying this card on the table and maintaining his complement of 8 cards by taking from stack. Penalty cards, ie divide 2 or equate to zero can be added to an opponents card flow, and certain cards require judgement decisions to be taken.
Patent FR-2261138-A1 (FR)
Title: Transfer printing by transferring pigmented polymeric layer - from flexible substrate to fabric under heat and pressure
IPC: D06P1/44
Filed: 1975-02-12
Abstract: A textile fabric is printed by being pressed into contact with a detachable layer (containing a colourant and a polymer) formed on a flexible substrate, the layer having been heated so that the polymer is rendered adhesive and the layer sticks to the fabric. The fabric and substrate are then separated so that the detachable layer remains secured to the fabric and the layer is then fixed to the fabric (pref. by heating) to form e.g. a printed pattern. The method may be used with synthetic or natural fibres. The method is quick and produces an accurate printed pattern which is well fixed in the fabric.
